▎ 摘　　要

NOVELTY - Multi-metal-based wear-resistant disc brake pad comprises 6-8% organic binder, 8-15% rare earth modified metal reinforcing material braided fiber, 5-10% nano-carbon-based modified metal powder, 8-15% inorganic reinforcing fiber, 10-20% friction performance modifier, 25-35% anti-wear lubricant, 5-10% inorganic nano-modified rubber powder, 5-8% high temperature inorganic binder, 3-8% grinding agent, and 15-30% space filler. The rare earth modified metal reinforcing material woven fiber comprises 40-60% rare earth modified stainless steel-manganese-titanium braided fiber, and 30-60% rare earth modified copper cotton-tungsten-aluminum braided fiber, and the surface of the braided fiber is wrapped with a high temperature resistant organic resin protective film. The nano-carbon-based modified metal powder comprises 40-60% graphene-modified copper powder, 20-30% carbon fiber-modified zinc powder, and 20-30% carbon nanotube-modified tin powder. USE - The brake pad is useful for passenger and cargo and to the braking conditions of automobiles when running at high speed and heavy load. ADVANTAGE - The brake pad has high strength, stable friction coefficient, good heat resistance, and wear resistance, high absorption power per unit area, high thermal conductivity, and comfortable braking with no noise, and less ash fall, which greatly improves the life of the product and solves the shortcomings of semi-metal-based brake pads e.g. high braking noise and easy brittleness at corners. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing multi-metal-based wear-resistant disc brake pad.
